The primary function of sensory neurons in the nervous system is to carry nerve impulses from receptors to the cell body. Sensory neurons are responsible for transmitting information from sensory receptors, which detect changes in the environment (such as light, sound, touch, taste, and temperature), toward the central nervous system (CNS) for processing. This pathway is crucial because it allows the body to perceive and respond to external stimuli, facilitating interactions with the environment.

Although other options present different functions related to the nervous system, they do not pertain specifically to the role of sensory neurons. For instance, transmitting impulses from the central nervous system to muscles is the function of motor neurons, which operate in the opposite direction—sending signals from the CNS to effectors like muscles. Connecting sensory neurons with motor neurons involves interneurons, which play a role in reflex actions and processing within the CNS, not in the direct function of sensory neurons themselves. While processing sensory information in the brain is a critical step in the overall function of the nervous system, it pertains to the higher functions of the brain rather than the direct role of sensory neurons in transmitting information from receptors to the cell body.
